Genetic diversity is essential to the security of agriculture. Without the availability of a wide range of plant varieties and the genetic resources they contain, crops cannot adapt to combat the ever-changing threats of pests, diseases and climatic change. Yet, with the increasing industrialisation of modern agriculture, farming has become a business which centres on a handful of new, genetically similar 'super seeds'. Plants must evolve in order to survive, but modern agriculture has replaced diversity with uniformity, and security with vulnerability. Saving the Seed traces the decline of crop varieties in European farming and describes what is being done to safeguard genetic resources for the future. Conservation efforts by government and industry suffer from serious drawbacks, with wrangles over ownership and control of resources. The crucial work is being done by individuals and grassroots organisations, who largely go unrecognised and under-resourced. What is urgently needed are sound policies to promote the diversification of agriculture and an integrated strategy for safeguarding the genetic base of our food system. Saving the Seed contains the most up-to-date information available on genetic resources in Europe and on those working to save them. Renee Vellve is a researcher at GRAIN, a no-governmental organisation working to promote the sustainable conservation and use of genetic diversity, based on grassroots approaches to genetic resources management.

Is it possible to see famines coming, to be prepared and to save possibly hundreds of thousands of lives?Or is this the wrong question? A famine is not a single natural catastrophe: it has different stages. Many societies have sophisticated strategies for coping ? but these are becoming dramatically limited.Famine Early Warning System is about the people who are caught up in the process of famine. Peter Walker looks at how they perceive their predicament and what they do to avert mass starvation: and at what genuinely useful help can be offered in order to prevent irreversible disaster.

Most of the world's population lives on or near the coasts. Every nation not completely landlocked has used the sea as its supposedly self-cleansing garbage dump. Now the effects are being felt. There is not a coast in the world which is not dangerously polluted. Sewage, oil, plastics, industrial effluents, radioactive waste have been added to ungoverned development, all of which are busily destroying otherwise robust inshore eco-systems. Hinrichsen, basing his work on United Nations Environment Programme (UNEP) research and his own extensive travels, has described the situation in the Mediterranean, the Gulf, the Indian Ocean, the South-East Asian Seas and the Eastern Pacific. He covers both the disasters and the growing successes in dealing with them, and he points the way to the sort of international deal needed to rescue a vast resource in danger of complete destruction. His book is both a call to action and a sign of hope.Originally published in 1990
We have always had land in which the agricultural productivity is limited because there is not enough moisture. Systems of farming and burning often degrade dryland further until it is desert. Today, however, the problem is becoming much more serious. Over 20 per cent of the world's population lives in dryland areas, and unless action is taken drylands will increase dramatically. This book focuses on the people who live and .farm in the drylands, their use of land resources and the economic returns from their decisions. In a clear and thorough economic appraisal, the authors show how it is still possible to arrest the problem. Originally published in 1989
Much of the world's tropical timber is still supplied from natural forest, but under current systems of management the forests are rapidly becoming exhausted. Unless management practices change to become genuinely sustainable, neither the forests nor the essential contribution of the timber industry to many economies will survive. Duncan Poore reviews the extent to which natural forests are already being sustainably managed for timber production, and looks at how these practices can be enlarged. He places management for timber in the wider context of tropical forest conservation and outlines a strategy for further action. Thoroughly researched and accessibly written, this book will be useful for everyone working or interested in the subject of tropical forests. Foreword by Dato Dr B.C.Y.

Over the last two decades, the topic of forest ecosystem services has attracted the attention of researchers, land managers, and policy makers around the globe. The services rendered by forest ecosystems range from intrinsic to anthropocentric benefits that are typically grouped as provisioning, regulating, supporting, and cultural. The research efforts, assessments, and attempts to manage forest ecosystems for their sustained services are now widely published in scientific literature. This volume focuses on broad-scale aspects of forest ecosystem services, beyond individual stands to large landscapes. In doing so, it illustrates the conceptual and practical opportunities as well as challenges involved with planning for forest ecosystem services across landscapes, regions, and nations. The goal here is to broaden the scope of land use planning through the adoption of a landscape-scale approach. Even though this approach is complex and involves multiple ecological, social, cultural, economic, and political dimensions, the landscape perspective appears to offer the best opportunity for a sustained provision of forest ecosystem services.
Containing contributions from researchers, engineers, planners, decision-makers and consultants, this book reviews topics such as: Earth's Materials and Resources; Earth's Dynamics; Geo-Environmental Planning and Management; Environmental Remediation; and Geo-Information Sources. It will be of interest to a diverse audience of researchers, practitioners and government employees including geologists, civil engineers, forest and agricultural engineers, geographers, biologists, ecologists, hydrologists, architects, and local planners.
The Brahmaputra River represents nearly 30% of India's water resources potential and 41% of its total hydropower. No sustainable future for this underdeveloped region can occur without a plan combining social, political, economic, cultural, and legal considerations with scientific paradigms. This book pools the talent, knowledge and experience of a wide range of water resource professionals to provide an exhaustive study of the Brahmaputra River basin, present and future.
Though the modern Spanish State was formed in the mid Fifteenth Century, historical records show that water works, statues, and the utilization of water dates back to centuries BC. As a semi-arid country, the effort to control, store and assure water supplies to cities and fields is present in numerous historical and political landmarks. Water policy in Spain has been the focus of Spanish-speaking scholars for decades, yet a comprehensive treatment of the subject has never before been published in English. Water Policy in Spain fills this gap by providing readers with a comprehensive, detailed account of the history of water policy in Spain from the beginnings of the 20th century to the present day. Part one presents a synopsis of the physical, economic, environmental and climatic bases of Spain, also covering corresponding political topics. Part two reviews the major constraints and opportunities that are relevant to face major water policy challenges. And part three is an in-depth account of water policy in the country. The issues closely examined include the way in which old water laws and institutions have been able to adapt to new sentimental and institutional challenges, including the significant change in the last decade to comply with the European Union 's Water Framework Directive (WFD). Like many semi-arid countries, climate change, drought risks and water pollution are cause for growing concerns in Spain and the country is still struggling to define a consistent and widely accepted set of policies to combat these threats. Spain 's current water policy is unique because it entails a complete tour de force with respect to what the country has been doing on water matters for centuries. As the WFD must be enforced in 27 States (representing 500 million Europeans), the lessons that can be learnt from the Spanish experience should catch the attention of water practitioners around the world.
The ability to anticipate the impacts of global environmental changes on natural resources is fundamental to designing appropriate and optimised adaptation and mitigation strategies. However, this requires the scientific community to have access to reliable, large-scale information on spatio-temporal changes in the distribution of abiotic conditions and on the distribution, structure, composition, and functioning of ecosystems. Satellite remote sensing can provide access to some of this fundamental data by offering repeatable, standardised, and verifiable information that is directly relevant to the monitoring and management of our natural capital. This book demonstrates how ecological knowledge and satellite-based information can be effectively combined to address a wide array of current natural resource management needs. By focusing on concrete applied examples in both the marine and terrestrial realms, it will help pave the way for developing enhanced levels of collaboration between the ecological and remote sensing communities, as well as shaping their future research directions. Satellite Remote Sensing and the Management of Natural Resources is primarily aimed at ecologists and remote sensing specialists, as well as policy makers and practitioners in the fields of conservation biology, biodiversity monitoring, and natural resource management.
The way in which energy is governed in China is driving its rising level of carbon dioxide emissions. This book analyses the nature of energy governance in China by combining ideas relating to transition management with institutionalist theories, which helps to identify factors which assist or constrain the country's path to a low-carbon economy.
This monograph provides, for the first time, a most comprehensive statistical account of composite sampling as an ingenious environmental sampling method to help accomplish observational economy in a variety of environmental and ecological studies. Sampling consists of selection, acquisition, and quantification of a part of the population. But often what is desirable is not affordable, and what is affordable is not adequate. How do we deal with this dilemma? Operationally, composite sampling recognizes the distinction between selection, acquisition, and quantification. In certain applications, it is a common experience that the costs of selection and acquisition are not very high, but the cost of quantification, or measurement, is substantially high. In such situations, one may select a sample sufficiently large to satisfy the requirement of representativeness and precision and then, by combining several sampling units into composites, reduce the cost of measurement to an affordable level. Thus composite sampling offers an approach to deal with the classical dilemma of desirable versus affordable sample sizes, when conventional statistical methods fail to resolve the problem. Composite sampling, at least under idealized conditions, incurs no loss of information for estimating the population means. But an important limitation to the method has been the loss of information on individual sample values, such as the extremely large value. In many of the situations where individual sample values are of interest or concern, composite sampling methods can be suitably modified to retrieve the information on individual sample values that may be lost due to compositing. In this monograph, we present statistical solutions to these and other issues that arise in the context of applications of composite sampling. Content Level Research
This book presents revealing case studies on carbon footprint calculation and mitigation in various industrial sectors. There are numerous sectors whose carbon footprints need to be calculated, and effective ways to mitigate the greenhouse-gas emissions from these sectors need to be found. Using representative case studies, this book highlights the carbon footprint of national power generation systems, crude glycerol production plants and the Brazilian highway network system, as well as the integration of renewable energy sources in expansion planning, so as to promote and implement power system decarbonization.

The book presents international approaches to the latest developments in both the fundamental bases and the applicability of state-of-the-art knowledge that can be effectively used for solving a variety of large problems in integrated water resources management. The main focus of the book is on water pollution - physical, chemical, biological, and geographical pollution, hydrology problems, and limnology tasks.
This book describes how NGOs' efforts to promote sustainable development are affected by their funding, management strategies, and relationships with government, communities, and other NGOs. The authors explore implications for theory and offer suggestions for increasing NGO effectiveness.
Photovoltaics, the direct conversion of sunlight to electricity, is now the fastest growing technology for electricity generation. Present "first generation" products use the same silicon wafers as in microelectronics. "Second generation" thin-films, now entering the market, have the potential to greatly improve the economics by eliminating material costs. Martin Green, one of the worlds foremost photovoltaic researchers, argues in this book that "second generation" photovoltaics will eventually reach its own material cost constraints, engendering a "third generation" of high performance thin-films. The book explores, self-consistently, the energy conversion potential of advanced approaches for improving photovoltaic performance and outlines possible implementation paths.
This book targets the issue of water scarcity in Egypt as a typical example of the world water crisis. Today, the available water resource is facing its limit because of rapid increase in water demand as a result of population growth and changes in peoples' life-style. The basic idea to solve the problem of water scarcity is that the irrigation sector, the biggest user of water, should increase water use efficiency. However, the real problem is how this can be achieved in view of the crucial need for water in this sector. This book addresses this challenge through case studies from the Nile delta in Egypt. The water problem in the Nile delta, the major source for water in Egypt, is discussed in this book from all its various aspects. This book covers the situation before and after the advent of the Aswan High Dam, so that the reader understands the entire development. Another special feature are the extensive and scientific descriptions of contemporary topics in water and agriculture, especially from the viewpoint of water saving and sustainability. These descriptions are based on field experiments and surveys in a six-year international research project. Topics of this book are local, but their implications are global.
Academics, community activists, and politicians have rediscovered regionalism, insisting that regions are critical functional units in a world-wide economy and, just as important, critical functional units in individual American lives. More and more of us travel across city, county, even state borders every morning on our way to work. Our television, radio, and print media rely on a regional marketplace. Our businesses, large and small, depend on suppliers, workers, and customers who rarely reside in a single jurisdiction. The parks, riverfronts, stadiums, and museums we visit draw from, and provide an identity to, an area much larger than a single city. The fumes, gases, chemicals, and run-off that pollute our air and water have no regard for municipal boundaries. This book lays out a variety of opinions on regionalism, its history and its future. While the essays do not comprise a debate, pro and con, about regionalism, they do provide a wide array of perspectives, based on the authors' diverse backgrounds and experience. Some contributors have made close academic studies of how regional action occurs, in various states like Minnesota, California, and Oregon; others give an historical account of a particular region like that surrounding New York City; and yet others point out aspects of regionalism--race, especially-- that should not be ignored. Why did past efforts at regional collaboration fall apart? What did regionalist efforts of decades ago leave undone, and what new goals should regionalists set? Without an understanding of these questions, policymakers and advocates may find themselves "reinventing the region." This book provides an important understanding of how regionalism has played out in the past, how policies shape places, and the possibilities and limits of regional action. Bruce J. Katz, director of the Brookings Institution Center on Urban and Metropolitan Policy, was formerly chief of staff at the U.S. Department of Housing and Urban Development.

'This book bridges disciplines, previously confined to specialist journal publications, by providing a comprehensive overview of the systems analysis application to water resources. It is ideal for Masters-level courses in Water Resources Engineering where modern management techniques of optimization and modelling are highly important in the strategic management of a vital resource.' - Derek Clarke, University of Southampton, UK 'The great novelty of this book is that it presents in detail how fuzzy-set theory can be used in water resource system management. The author was one of the pioneers who opened up this new field and is considered to be one of the greatest experts in it.' - Rodolfo Soncini Sessa, Politecnico di Milano, Italy Water resources management is increasingly interdisciplinary and must take into account complex socioeconomic factors and environmental variables. This book describes the 'systems approach' and its application to contemporary water resources management, focusing on three main sets of tools: simulation, optimization and multi-objective analysis. This approach is presented within the context of sustainable planning and development under conditions of uncertainty. Managing Water Resources: Methods and Tools for a Systems Approach introduces system dynamic simulation as a tool for integrated modelling and contains coverage of the use of fuzzy sets for incorporating objective and subjective uncertainties. The book combines theory with many practical examples, as well as including programs and exercises on downloadable resources. It comprises both an advanced text for students of water resources and civil or environmental engineering and a practical guide for professionals. Published jointly with UNESCO and International Hydrological Programme
Public debate has stimulated interest in finding greater compatibility among forest management regimes. The debate has often portrayed management choices as tradeoffs between biophysical and socioeconomic components of ecosystems. Here we focus on specific management strategies and emphasize broad goals such as biodiversity, wood production and habitat conservation while maintaining other values from forestlands desired by the public. We examine the following proposition: Commodity production (timber, nontimber forest products) and the other forest values (biodiversity, fish and wildlife habitat) can be simultaneously produced from the same area in a socially acceptable manner. Based on recent research in the Pacific Northwest, we show there are alternatives for managing forest ecosystems that avoid the divisive arena of 'either-or' choices. Much of the work discussed in this book addresses two aspects of the compatibility issue. First, how are various forest management practices related to an array of associated goods and services? Second, how do different approaches to forest management affect relatively large and complex ecosystems?
Switching off the pumps of a mine is one of the last steps in the lifetime of a surface or underground mine. As the water in the open space raises, the water might become contaminated with different pollutants and eventually starts to flow in the open voids. This book addresses the processes related to mine abandonment from a hydrogeological perspective. After an introduction to the relevant hydrogeochemical processes the book gives detailed information about mine closure procedures. Based on in-situ measurements the hydrodynamic processes in a flooded mine are described and some of the mine closure flow models exemplified. As all investigations base on precise data, the book gives some key issues of monitoring and sampling, especially flow monitoring. Then the book shows some new methodologies for conducting tracer tests in flooded mines and gives some hints to passive mine water treatment. At the end 13 well investigated case studies of flooded underground mine and mine water tracer tests are described and interpreted from a hydrodynamic point of view. |
